Zorin doesn't boot after failed upgrade from 16 to 17 (Alert! UUID does not exist)

Pixor · 1 February 2024 18:44

Hi, today I used Zorin's upgrade tool to upgrade my system from Zorin 16.3 to Zorin 17. After the app finished updating packages, it printed a DPKG error message. Then, I tried it again, but also received an error message. For both errors, I saved the output to a file and clicked on the "report and close" button.

When restarting the system, however, Zorin fails to boot; only BusyBox launches, giving me an initramfs console where it says:

Gave up waiting for root file system device. Common problems:
  - Boot args (cat /proc/cmdline)
    - Check rootelay= (did the system wait long enough?
  - Missing modules (cat /proc/modules; ls /dev)
ALERT! UUID=f3f553e1-4043-499f-8dd7-847656680445 does not exist. Dropping to a shell!

Following advice from other forums, I opened the BIOS and switched from RAID to AHCI, which hasn't helped.

I've set up dual boot with Windows 11, which fails to boot as well, giving me a bluescreen with the stopcode INACCESSIBLE_BOOT_DEVICE.

My machine is a Dell Inspiron 14 7400 laptop with an 11th Gen Intel® Core™ i7-1165G7 @ 2.80GHz × 8.

What to do now? How can I fix this and return to a usable state without having to reinstall everything from scratch? I don't care about the upgrade anymore, I just want to continue using my computer as before, including my data.

I would first try using a LiveUSB of Zorin OS to repair EFI boot with Grub repair.
This should help at least ensure you can boot Windows.
https://help.ubuntu.com/community/Boot-Repair

It's obviously looking for a drive by UUID in /etc/fstab.

sudo blkid

That'll list your drives... ensure fstab has the correct drives listed.

For instance, here's the fstab entries for my EFI partition and swap drives:


# EFI
UUID=B2C2-C122												/boot/efi									vfat	umask=0022,fmask=0022,dmask=0022,x-gvfs-show,noatime	0		0

# SWAP
UUID=f51c1888-c76e-4f16-b25e-2ba99b697696					none										swap	discard,noatime,pri=1									0		0
UUID=d4398e10-8183-4a5a-88a6-9d830a6f2a6d					none										swap	discard,noatime,pri=1									0		0
UUID=c39fbec2-4aa6-4255-b6c3-e9540b397713					none										swap	discard,noatime,pri=1									0		0

I'd try to find the drive it should be looking for via sudo blkid, then boot the Zorin OS Boot USB, edit /etc/fstab on the system drive, correct the incorrect entry, then try booting again.

I booted into Zorin 17 on a live USB stick and installed Boot-Repair. First, it told me that the SSD/partition is nearly full (this could be a cause of the issue, right?), so I permanently deleted various files using rm. Currently, there's 38.6 GB of free space in the partition, out of 737.2 GB in total.

After that, however, Boot-Repair just said grub-efi-amd64-signed purge cancelled. and didn't do anything else. Here's the output of Boot-Repair: https://sprunge.us/sTUKhW

Where is the /etc/fstab file located that I should edit - on the Zorin partition itself?

I'm not sure of your particular setup, but I'm betting the above should be "5A83-06BE" or "96D484DED484C24B".

You'll just have to figure out which partition Zorin OS is booting from, and substitute that UUID for what is in there now.

If it is actually on /dev/nvme0n1p7, then about the only thing you can do is reinstall, since something is broken on that partition that won't let it boot.

Do a backup first if you've saved any personal files in the directories provided by Zorin OS. I recommend not using those, instead using directories on an external drive for your personal files. Or bind-mounting those Zorin OS-provided directories to redirect to directories on an external drive.

That way, you can completely wipe the OS drive(s) if you wanted, and your personal files aren't touched.

Aravisian · 1 February 2024 21:09

Yes, it absolutely can. Only 38gigs freed now out of 740 gigs? That's... that's a lot of stuff...
I think this adds some clarity to your situation. During the upgrade, your drive / partition was filled and it ran out of space.

Pixor · 1 February 2024 22:11

I changed it to 5A83-06BE, but nothing would boot anymore, not even the live USB stick; I only get a grub> command line.

Luckily, I was able to boot back into the live USB drive:

grub>set root=(hd1,?)  # I already forgot the partition number
grub>chainloader /efi/boot/grubx64.efi
/EndEntire
grub>boot

Note that, in the live version of Zorin with the SSD's Zorin partition unmounted, sudo fsck -p /dev/nvme0n1p7 and sudo fsck -a /dev/nvme0n1p7 both return everything clean.

I tried running Boot-Repair without the purge GRUB before reinstalling option, and then it did not output the purge cancelled error anymore. It said that the "boot sector was successfully repaired". However:

Locked-NVram detected. Please do not forget to make your UEFI firmware boot on the Zorin OS 16.3 (16) entry (nvme0n1p1/efi/ubuntu/shimx64.efi file) ! Please disable SecureBoot in the BIOS. Then, try again.

I did disable SecureBoot but that alone hasn't changed anything yet. What exactly am I supposed to do regarding the nvme0n1p1/efi/ubuntu/shimx64.efi file? And what does Locked-NVram mean (i.e. what to do)?

Boot-Repair Summary

boot-repair-4ppa2075                                              [20240202_0058]

============================= Boot Repair Summary ==============================




Default settings: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to sign-grub) and reinstall the grub-efi-amd64-signed of
nvme0n1p7,
using the following options:  nvme0n1p1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your UEFI firmware boot on the Zorin OS 16.3 (16) entry (nvme0n1p1/efi/****/shim****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\shim****.efi (**** will be updated in the final message)

User settings: _________________________________________________________________

modprobe: FATAL: Module efivars not found in directory /lib/modules/6.2.0-39-generic
The settings chosen by the user will reinstall the grub-efi-amd64-signed of
nvme0n1p7,

Is there anything else I could try before having to reinstall Zorin?

Also, what about Windows? Could at least it be kept without reinstallation?

Btw. thank you both very much for your quick help already

NVRAM is Non Volatile RAM.
This RAM is a part of the motherboard and stores critical init data for the motherboard. Clearing it or resetting it is most often done by resetting CMOS. This is usually a remove and replace battery physical action, or resetting the CMOS jumpers.

It being Locked means that the memory is filled and not being cleared. Though this is most commonly seen in Windows, due to Windows maintaining control over aspects of hardware in order to give the semblance of a Fast Boot, it can happen for a large number of reasons. The best thing to do is to clear it out. In your case, it seems likely that the upgrade or installs filled the memory.

It also shows that Zorin OS lacks a file in efi. If Windows is not booting either and EFI variables are not supported - all of this leads me to suspect that the EFI partition is corrupted.

In short, if a bad sector or block failed that was present on the drive where the EFI partition resides, that entire partition is ruined.
A new EFI partition can be created and the efi boot files placed on it, however.

The above links are to show it is possible, not intended to be a full guide for you to follow immediately.

While I remain unable to repair Zorin, I was in fact able to create a "Windows 11 installation medium" using a different computer and to boot from it. In the recovery menu, I selected the first option which was supposed to fix booting issues. It exited with an error message, but after restarting, Windows 11 did, in fact, boot correctly. Now, Windows 11 boots and works fine again with no data loss!

However, I still cannot boot Zorin. I tried following this German tutorial on EFI troubleshooting, executing the following commands in the live version of Zorin 17 booted again from a USB drive:

$ mount /dev/nvme0n1p7 /mnt
$ mount /dev/nvme0n1p1 /mnt/boot/efi
$ for i in dev dev/pts proc sys sys/firmware; do mount --bind /$i sudo /mnt/$i; done
$ sudo chroot /mnt
$ update-grub
$ grub-install
$ exit
$ reboot

After that, I tried this:

zorin@zorin:~$ sudo update-grub2
Sourcing file `/etc/default/grub'
Sourcing file `/etc/default/grub.d/init-select.cfg'

Found Zorin OS 16.3 (16) on /dev/nvme0n1p7

done

None of that repaired Zorin's EFI, but instead removed Windows 11's Grub entry. (Though, I can still boot Windows 11 by accessing it from the BIOS.)

Is there anything else I can do to fix Zorin?

Boot Repair Summary

boot-repair-4ppa2056-zorin1                                              [20240203_0119]

============================= Boot Repair Summary ==============================




Default settings: ______________________________________________________________

The default repair of the Boot-Repair utility would purge (in order to unsign) and reinstall the grub-efi of
nvme0n1p7,
using the following options:  nvme0n1p1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your UEFI firmware boot on the Zorin OS 16.3 (16) entry (nvme0n1p1/efi/****/grub****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\grub****.efi (**** will be updated in the final message)

User settings: _________________________________________________________________

modprobe: FATAL: Module efivars not found in directory /lib/modules/6.2.0-39-generic
ls: Zugriff auf '/sys/firmware/efi/vars' nicht möglich: Datei oder Verzeichnis nicht gefunden
The settings chosen by the user will not act on the MBR.
Additional repair will be performed: unhide-bootmenu-10s



Unhide GRUB boot menu in nvme0n1p7/boot/grub/grub.cfg

Your Boot repair log looks normal.

Are you seeing a Windows OS Chooser at boot?

Pixor · 3 February 2024 13:06

When starting the computer, Grub appears and only lets me boot Zorin:

All of these four "advanced" options just result in the initramfs command line:

The Grub configuration for Zorin that appears when pressing e (Discourse wouldn't let me upload a photo of it):

setparams 'Zorin'
    recordfail
    load_video
    gfxmode $linux_gfx_mode
    insmod gzio
    if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
    insmod part_gpt
    insmod ext2
    search --no-floppy --fs-uuid --set=root f3f553e1-4043-499f-8dd7-847656680445
    linux        /boot/vmlinuz-5.15.0-92-generic root=UUID=f3f553e1-4043-499f-8dd7-847656680445 ro  quiet splash i8042.nomux i8024.noloop $vt_handoff
    initrd        /boot/initrd.img-5.15.0-92-generic

Is it correct that it says vmlinuz instead of vmlinux?

In order to boot Windows 11, I have to press F12 during startup to access the BIOS/UEFI:

Then, the Windows 11 loading circle appears to reveal the login screen a few moments later.

Note that both the ubuntu and the UEFI Micron 2300 NVMe options result in the initramfs console being shown.

More screenshots from the BIOS

Aravisian · 3 February 2024 17:29

Strangely, yes...

Zorins Grub is not running the OS Prober - and it fails the initramfilesystem. The BPF= Invalid name shows that the kernel is sourcing two different kernels.
Is accessing the drive using LiveUSB to retrieve and backup your personal files and reinstalling Zorin OS on that partition a viable option for you?

Pixor · 3 February 2024 19:22

I do have several redundant backups of my personal files in the Zorin partition, so I wouldn't lose those. Thus, I would, of course, freshly reinstall Linux if there's no way to repair the Zorin installation. (Although I might choose Fedora over Zorin because I have noticed that I need a very up-to-date system, especially for software development. Leaving Zorin would be quite sad as it's the most beautiful distro I've ever seen. )

However, I would strongly prefer to (at least try to) repair Zorin so I could avoid having to set up everything from ground zero, namely installed apps and configurations. Another point is that I currently don't really have the time required for extensive setup. Perhaps I'll just wait for a couple of weeks until I've got significantly more leisure time.

As always, I'd be very grateful for any recommendations

Aravisian · 3 February 2024 20:00

With strong backups at the ready, you could try running fsck using a LiveUSB (Never run fsck on your loaded mounted Zorin OS) or try initramfs repair.

Pixor · 4 February 2024 03:05

Major success!

First, I ran sudo fsck.ext4 /dev/nvme0n1p7 but it didn't help.

Then, I tried to add a delay to the root partition being loaded, following this German tutorial, but it didn't help either:

(initramfs) cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-5.15l.0-92-generic root=UUID=f3f553e1-4043-499f-8dd7-847656680445 ro  quiet splash i8042.nomux i8024.noloop $vt_handoff rootdelay=5

Also, ls /dev/mapper returns just controle, which, according the the tutorial, means that "there is no root directory present". The "subsequent activation of the volume" using vgchange -ay didn't work either. blkid returned nothing.

(initrams) cat /proc/modules
crc32_pclmul 16384 0 - Live 0xffffffffc0431000 (E)
xhci_pci_renesas 20480 0 - Live 0xffffffffc0482000 (E)
pinctrl_tigerlake 32768 0 - Live 0xffffffffc0317000 (E)

Then, however, I tried this:

zorin@zorin:~$ sudo mount /dev/nvme0n1p7 /mnt
zorin@zorin:~$ sudo mount /dev/nvme0n1p1 /mnt/boot/efi
zorin@zorin:~$ sudo mount --bind /dev /mnt/dev
zorin@zorin:~$ sudo mount --bind /dev/pts /mnt/dev/pts
zorin@zorin:~$ sudo mount --bind /proc /mnt/proc
zorin@zorin:~$ sudo mount --bind /sys /mnt/sys
zorin@zorin:~$ sudo chroot /mnt
root@zorin:/# sudo grub-install /dev/nvme0n1

grub-install: Warning: EFI variables cannot be set on this system.
grub-install: Warning: You will have to complete the GRUB setup manually.
installation finished. No errors occurred.
root@zorin:/# update-initramfs -u

And I did this:

zorin@zorin:~$ sudo grub-install --boot-directory=/mnt/boot /dev/nvme0n1
x86_64-efi is being installed for your platform
installation finished. No errors occurred.
zorin@zorin:~$

Now, Zorin finally booted again, yayyy!

As expected, all my files and installed programs are still there, everything works again. The only issue is that the incomplete upgrade has indeed updated Gnome to version 43, but it didn't install all the Zorin customisations, so that I currently have Zorin 16.3 looking nothing like Zorin.

Fixed permissions issue

I opened the Zorin system updater app and clicked on the Upgrade button. Then, Gnome's authentication popup opened, saying:

Incorrect permissions on /usr/libexec/polkit-agent-helper-1 (needs to be setuid root)

The "Authenticate" button is greyed out, and when pressing the "Cancel" button, nothing happens, so I can't even close the popup. What to do?

me@dell-zorin:/usr/libexec$ ls -l polkit-agent-helper-1
-rwxr-xr-x 1 root root 18736 Feb 26    2022 polkit-agent-helper-1

This prevented the popup from re-appearing:

me@dell-zorin:/$ sudo chmod 4755 /usr/lib/policykit-1/polkit-agent-helper-1

Fixed APT Upgrade

Now, when opening Zorin's upgrader tool and clicking on the "Upgrade" button, the following error message appears:

I did this now:

me@dell-zorin:~$ sudo dpkg -i --force-overwrite /var/cache/apt/archives/libdc1394-dev_2.2.6-4_amd64.deb
me@dell-zorin:~$ sudo apt-get update
me@dell-zorin:~$ sudo apt-get upgrade

Immediately after fixing the APT upgrade (i.e. without rebooting), the system already said it's Zorin 17:

me@dell-zorin:~$ lsb_release -a
No LSB modules are available.
Distributor ID:	Zorin
Description:	Zorin OS 17
Release:	17
Codename:	jammy

In the system settings under "Info", it says:

Name of the operating system: Zorin OS 17 Core

After rebooting, everything looks more like Zorin:

Successfully repaired Zorin Appearance

The only noticable issue left is that the spatial desktop is not available and that Zorin Appearance won't launch (which both are likely the same issue).

Thus, I did this:

me@dell-zorin:~$ sudo apt install --reinstall zorin-os-desktop
me@dell-zorin:~$ zorin-appearance
(zorin-appearance:36077): GLib-GIO-ERROR **: 19:20:13.594: Settings schema 'org.gnome.shell.extensions.zorin-desktop-icons' does not contain a key named 'use-nemo'
Trace/Breakpoint triggered
me@dell-zorin:~$ sudo apt-get --reinstall install zorin-appearance
me@dell-zorin:~$ sudo apt dist-upgrade
me@dell-zorin:~$ sudo apt-get --reinstall install zorin-appearance-layouts-shell-core
me@dell-zorin:~$ sudo apt-get --reinstall install zorin-appearance-layouts-support
me@dell-zorin:~$ sudo apt-get --reinstall install zorin-auto-theme

Now, Zorin Appearance launches again and the spatial desktop appeared after a reboot.

Manually updated the kernel

For some reason, the kernel was not updated during the interrupted upgrade, so that I had a Zorin 17 installation with Linux 5.15 instead of 6.2. That's why I decided to update the kernel manually, following this tutorial: Ubuntu 22.04 Users Can Now Upgrade to Linux Kernel 6.2 - OMG! Ubuntu

me@dell-zorin:~$ uname -a
Linux dell-zorin 5.15.0-92-generic #102-Ubuntu SMP Wed Jan 10 09:33:48 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
me@dell-zorin:~$ sudo apt install linux-generic-hwe-22.04
me@dell-zorin:~$ sudo reboot
me@dell-zorin:~$ uname -a
Linux dell-zorin 6.5.0-15-generic #15~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Fri Jan 12 18:54:30 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

The system still works fine, so I think the kernel update was successful.

(Hopefully) the last issue

Immediately after booting, Zorin warned me (and still does so after each reboot) that there are only a few MB of space left on the EFI partition. Is that problematic? What should I do about that?

mckenzm · 6 February 2024 05:21

You are dual booting,it is mostly Microsoft. Fonts, maybe the new one.. The partition is small in any case.
